Abstract

The invention relates to a workpiece pressure testing device and relates to the field of hardware machining equipment. The workpiece pressure testing device comprises a base, a supporting column and a pressure push rod. One end of the supporting column is fixed to the base, a worktable is further arranged on the base and located on one side of the supporting column, and the pressure push rod is installed at the other end of the supporting column and fixed above the worktable in a suspending mode. The worktable is provided with a fixture installation groove, a counter is further arranged on the supporting column and provided with a photoelectric induction head, and the photoelectric induction head is aligned with the worktable. The workpiece pressure testing device can obtain an effective result and effective testing data, and the detection pressure can reach the needed standard; meanwhile, workpieces can be counted, leakage detection of workpieces can be avoided, and the testing effectiveness and stability are improved to a certain extent.

Description

technical field

[0001] The invention relates to the field of hardware processing equipment, in particular to a hardware pressure testing device. Background technique

[0002] In the production process of hardware accessories, it is usually necessary to carry out a pressure test on the developed product. For example, the trumpet-shaped workpiece is made of polymer materials. In order to verify the feasibility of its material, a pressure test of 10MPa~12MPa is required, even reaching 22MPa. , the test device with the traditional static pressure sealing structure design leaks during the test and cannot meet the test requirements. For example, the Chinese invention patent "Simple Pressure Tester", with application number 201210352159.0, discloses a jacking cylinder that includes a manual hydraulic pump and is connected to the manual hydraulic pump through an oil circuit. The top of the jacking cylinder is fixed on On the base, an inverted U-shaped test platform is fixed on the ...
